A delicate yet eerie potion bottle made of cracked porcelain, with fading floral engravings and a lace-like silver filigree top. The liquid inside is a swirling deep crimson, occasionally forming the shape of ghostly hands. The cork is wrapped in black lace, and faint whispers can be heard when uncorked. 3D, ultra-detailed, gothic elegance, dark magical aura, 4K render.
